Chronic brain hypoperfusion
WebJan 16, 2024 · It is postulated that chronic cerebral hypoperfusion (CCH) is a major cause of VCI. CCH activates a molecular and cellular injury cascade that leads to breakdown of the blood brain barrier (BBB) and neurodegeneration. WebMar 13, 2024 · Chronic cerebral hypoperfusion (CCH), refers to a group of brain dysfunction syndromes caused by long-term decreased cerebral perfusion ( Ciacciarelli et al., 2024 ).
